Fuel System

The function of the fuel system is to collect and then deliver fuel to the cylinder chamber of your car’s engine. Here in the cylinder chamber the fuel is mixed with air as it vaporizes and then the mixtures burns to produce energy. That energy is then converted into a rotary motion that powers your car.

The fuel system
components are: the fuel tank, fuel lines, fuel pump and the fuel filter.

Fuel Pump: Draws the fuel from the tank and propels it through
fuel lines.

Fuel Lines: Steel lines and flexible hoses
carry the fuel from the tank to the engine.

Fuel Filter: The fuel filter is important for
keeping your fuel system functioning at its best. A clean fuel filter means
better gas mileage. (Change every 15,000
miles or once a year.)

Fuel
system wear and tear can be affected by the quality of fuel used in your
automobile, the age of your car or truck, driving conditions, maintenance
history and the number of miles on the vehicle.

Potential fuel system related problems
that you may or may not experience some time in the life of your vehicle
include: poor gas mileage, “won’t start”, difficulty starting, check engine light
appearing on the dashboard, stalling,surging, misfiring or hesitating.

EGR (Exhaust Gas Recirculation)
Carbon deposit is the number one issue related to the fuel system. The
by-product of burning gas is soot,carbon build-up. That carbon build-up acts
like a sponge. As gas is burned carbon deposits build up on the fuel system
components. The deposits soak up fuel causing the car to think itw is running
lean and the cars on-board computer tells the fuel system to deliver more fuel.
Once the deposits are saturated the car will adjust back. This process has the
biggest impact on fuel economy. As the deposits grow, the harder the fuel
system has to work, causing poor fuel economy. Fuel injectors, intake valves,
exhaust valves,
